What action can be taken with the changes made to a document marked as final?

The correct action regarding changes made to a document marked as final is that they cannot be overwritten. When a document is marked as final, it typically indicates that the document is in a state that should not be edited further to preserve its integrity. This protects the content from unintentional modifications and signifies that the content is considered complete and approved for circulation or distribution.

In this context, marking a document as final acts as a safeguard against changes that could alter its meaning or intent. Therefore, attempting to overwrite the document would go against the purpose of marking it as final, which is to maintain the original content as is.

The other options suggest varying degrees of editing or saving capabilities that do not align with the intent of marking a document as final. It is essential to understand that the primary function of this feature is to provide a degree of security to the document's content, which is why the inability to overwrite changes is the accurate understanding.
